[Mauiusers] FS advanced setup question

Hi all,
is there any way for setting a UNIX group into a QOS based on
UNIXgroup+CLASS ?
I.e:
GROUPCFG[group1] CLASSCFG[gmedium_sl5] FSTARGET=10 QDEF=qos1
GROUPCFG[group2] CLASSCFG[glong_sl5] FSTARGET=10 QDEF=qos2
QOSCFG[qos1] FSTARGET=10
QOSCFG[qos2] FSTARGET=90
Anyone has some kind of similar conf in its cluster?
any approach?
Cheers,
Arnau
